Frequently Asked Questions

Windows may show a USB drive as RAW or say it must be formatted before use. If the files matter, cancel that prompt. Formatting or running a repair command before recovery can change the records a scan needs.

What RAW Means for Your Files

RAW is Windows' description when it cannot recognize a usable file system on the volume. The USB device may still expose sectors that a recovery program can read, but it may also be failing physically. RAW is a symptom, not a precise diagnosis.

Check Disk Management for the device's capacity and whether Windows sees it consistently. If it appears as zero bytes, repeatedly disconnects, or is not detected at all, software scanning may not be appropriate.

Before You Scan

Try a different known-good USB port or reader without formatting the device. Do not run CHKDSK or initialize the volume before you have secured recoverable files.

Prepare a healthy output drive with more free space than the data you need. Note the USB's approximate capacity so you can recognize it even if its drive letter disappears.

Recover Files From the RAW USB Device

Qiling Deep Data Recovery provides the scan modes shown below. The mode in Step 2 is chosen for this specific loss scenario; it does not change the need for a separate recovery destination.

Step 1. Keep the RAW Drive Unchanged

Cancel Windows' format prompt and connect a separate output drive. Install Deep Data Recovery on the PC, not on the RAW USB device.

Step 2. Choose USB/SD Scan

Select USB/SD Scan for a removable flash drive. If the volume was deliberately formatted, Format Scan may be a better first choice; RAW alone does not mean it was formatted.

Step 3. Identify the USB Device

Choose the USB drive by its physical size and label in the location view. If it is absent there despite a working connection, stop rather than guessing another disk.

Step 4. Inspect the Found Files

Let the scan complete, filter by file type, and preview important documents or photos. Use Deep Scan if the first pass is incomplete and the hardware remains stable.

Step 5. Recover to Another Disk

Select usable files, click Recover, and choose the separate output disk. Confirm that the copies open before attempting any file-system repair or reformat.

What to Do After the Files Are Safe

Only after verifying the recovered files should you decide whether to test or reformat the USB drive. A device that repeatedly turns RAW may be unreliable and should not hold the sole copy of important data.

If scans repeatedly stop due to read errors, minimize use and consider professional imaging. Continuing to power-cycle an unstable device can make recovery harder.

Frequently Asked Questions

Will formatting a RAW USB drive make the files accessible?

It may make the drive usable again but can remove recovery clues. Recover important files first.

Can CHKDSK fix RAW without data loss?

CHKDSK may refuse a RAW volume or alter metadata. Do not use it as the first data-recovery step.
